Hello :0) I'm new here, nice to meet you all! We have raised registered Quarters & Paints for almost 30 years.
Your mare is beautiful & has awesome bloodlines. Good food & love will take her where she needs to be :0)
We stand a red dun AQHA stallion who is Doc Bar bred and I am a big Lightning Bar fan. I love researching bloodlines. If you are interested, the Quarter Horse Legends books tell lots of great stories about these horses.
As far as your mare goes for HERDA, she would have shown signs of it by now, so don't worry about her, it would be good to test her if you plan to breed her. Both parents would have to have the gene to get a foal with herda, so if she has the gene, you just breed to a stallion who does not. The number of carriers looks like quite a few but last I had heard actual diagnosed cases were just over 200 in like 30 years. Might be more now but most of the vets I know here in Minnesota have never seen a case of HERDA. Great to know about but not all that common here. But then I am not in the middle of cutting horse country, you might see it more common there.
I was much more worried about HYPP.
Enjoy your beautiful mare :0) Jo
Here's some HERDA info:
The disease is found primarily in the American Quarter Horse
, specifically in cutting
horse lines. Affected horses have been found to trace to the stallion Poco Bueno
, or possibly, farther back to one of his ancestors.
Researchers have now named four deceased Quarter Horse stallions that were carriers and produced at least one affacted HERDA foal; they are Dry Doc, Doc O'Lena
, Great Pine, and Zippo Pine Bar
. These stallions all trace to Poco Bueno
through his son and daughter Poco Pine and Poco Lena
. Other breeds affected are the American Paint Horse
(APHA), and the Appaloosa
(ApHC) and any other breed registry that allows outcrossing to AQHA horses.
HERDA is characterized by abnormal skin along the back that tears or rips easily and heals into disfiguring scars. The skin is loose, and hyper-elastic in affected horses. Symptoms typically don’t appear until the horse is subjected to pressure or injury on their back, neck or hips, usually around two yrs of age. However foals can show signs when injured, while other horses mature and only show signs in the joints.
The expected lifespan of an affected horse is 2–4 years. There is currently no cure for this disease. To prevent it from occurring, the only solution is not to breed horses who both carry the HERDA gene.
